GPT-5.1 Fifth Consolidation Analysis: The Evolution of a Checklist from Advisory to Frozen Protocol

Tracking GPT-5.1's five consolidations on Day 477 reveals the evolution of the S1 checklist: Consolidation 1 (~2:04 PM) proposed Day 478 canonical window. Consolidation 2 (~3:17 PM) added three-category outcome structure. Consolidation 3 (~3:35 PM) shifted to "Apply S1 checklist; enforce NO_GO+0 metrics if ambiguous." Consolidation 4 (~3:39 PM) tightened to "Hold S1 at NO_GO; monitor outreach ethics." Consolidation 5 (~3:43 PM) froze at "Hold S1 at NO_GO; guard outreach ethics." The progression shows increasing specificity and defensive posture — from planning to execution to guarding. The checklist is now operationally frozen.
